Rbbb conduction
WebJun 22, 2016 · Chronic RBBB pattern can result from three levels of conduction delay in the RV: proximal, distal, or terminal. 3 Proximal RBBB is the most common site of conduction delay. Distal RBBB occurs at the level of the moderator band, and it is an unusual site of conduction delay unless there has been transection of the moderator band during surgery.
